One dies from dengue fever in Pingtung: CDC

HEALTH CONSCIENCE:The Centers for Disease Control reiterated the need to eliminate potential mosquito breeding sites to reduce the spread of dengue fever

The first fatal case of dengue fever this year has been reported in Pingtung and was among the 13 locally acquired dengue infections confirmed last week, the Centers for Disease Control (CDC) said yesterday.

Five imported and 13 locally acquired cases of dengue infection were reported last week, with all of the locally acquired cases coming from Pingtung County, the centers said, adding that 152 of the total 164 locally acquired infections confirmed so far this year were reported in the county, with the remainder reported in Taipei, New Taipei City (新北市) and Greater Kaohsiung.

The fatal case involved a 76-year-old woman with a history of high blood pressure who started to exhibit symptoms of loss of appetite, dry mouth, headache, nausea, vomiting, diarrhea, muscle pain and joint pain on Oct. 6 and was diagnosed with dengue infection after seeking medical attention.

She fell unconscious after falling down several times on Thursday, and died the next day, despite being taken to an emergency room for treatment, the centers said.

“She was diagnosed with intracerebral hemorrhage when she was taken to the hospital after her falls. So the direct cause of death was a brain hemorrhage as a result of her falls,” CDC physician Philip Lo Yi-chun (羅一鈞) said.

“Her death was associated with dengue fever because the infection had caused [a low platelet count in her blood]. The dengue infection and the decrease of platelets in her blood were the indirect cause of her death,” he said.

Three of the woman’s four family members have since been diagnosed with dengue fever, the centers added.

The centers reiterated the importance of domestic hygiene and the need to eliminate potential mosquito breeding sites to reduce mosquito density in surrounding communities.

Meanwhile, the centers said 117 cases of acute hepatitis A virus (HAV) have been reported this year as of Saturday last week, underscoring the importance of food hygiene as 40 percent of the cases had reported a history of eating raw food.

Eighty-six of the 117 reported acute HAV infections were locally acquired and 31 were imported, the centers said.

Further investigations have showed that 40 percent of the infected had eaten raw food at some point before the onset of the disease, of which 36 percent reported to have eaten raw seafood.

High-risk food items associated with HAV infection include shellfish, such as raw oysters, mollusks and scallops, fruits, such as frozen blueberries and raspberries and semi-dried tomatoes, and raw scallions and salads.

As sanitary conditions have improved in the past years, most children and teenagers do not have antibodies against the virus, and are susceptible to infection when coming into contact with virus-contaminated food and water, the centers said.

Following good food hygiene practices, the Food and Drug Administration has listed HAV screening as one of the mandatory tests to be done at food handlers’ health examinations to reduce the risk of the virus spreading through food.

HAV is passed on via the fecal-oral route by consuming HAV-contaminated food or water, the centers said.

The incubation period for the disease ranges between 15 days and 50 days, with those infected experiencing symptoms such as fever, fatigue, loss of appetite, vomiting and abdominal pain, before developing jaundice a few days later.
